Continuum Bridge Client

0.0.1 verified Sat Apr 25 auth: no javascript

The Continuum Bridge Client package is a development library for Raspberry Pi devices interacting with the Continuum Bridge platform (stable version 0.0.1, early development stage). It provides tools to interface with bridge components, handling communication and data exchange. Differentiators include minimal dependencies and direct Raspberry Pi GPIO integration. Release cadence is irregular as it's a prototype. Alternatives include platform-specific SDKs like AWS IoT or Azure IoT Edge.

Common errors

error Cannot find module 'client' ↓

cause Package not installed or installed globally without local node_modules.

fix

Run npm install client --save in project directory, or check NODE_PATH.

error TypeError: client.connect is not a function ↓

cause Using default import instead of named import for Client class.

fix

Use const { Client } = require('client') instead of const Client = require('client').

error Error: EACCES: permission denied, open '/sys/class/gpio/export' ↓

cause User lacks permission to access GPIO on Raspberry Pi.

fix

Run script with sudo, or add user to gpio group and reboot.

Warnings

gotcha Package is in early development (pre-1.0.0) — API may change without notice. ↓

fix Pin to exact version and expect breaking changes.

breaking Requires Node.js 12+ (engines field is *, but actually needs ES2017 features). ↓

fix Use Node.js 12 or newer; older versions may fail with syntax errors.

gotcha No default export; must use named exports const { Client } = require('client'). ↓

fix Use destructuring or require('client').Client.

gotcha On Raspberry Pi, GPIO access requires running as root or with sudo. ↓

fix Run script with sudo or add user to gpio group.

Install

npm install client

yarn add client

pnpm add client

Imports

Client

wrong

import Client from 'client'

correct

const Client = require('client')

Package does not support ESM; CommonJS only.

Client
wrong
```
const client = require('client')
```
correct
```
const { Client } = require('client')
```
Default export is not the Client class; destructure to get it.

config

wrong

const config = require('client/config')

correct

const { config } = require('client')

No submodule exports; config is exported from main.

Quickstart

Shows how to require the package, instantiate the client, connect, and send periodic data.

const { Client, config } = require('client');
const client = new Client({ apiKey: process.env.API_KEY ?? '' });
client.connect()
  .then(() => console.log('Connected'))
  .catch(err => console.error(err));
setInterval(() => client.send({ temp: 22.5 }), 5000);
